The Real Howard Spitz (1998)
Howard Spitz, played by Kelsey Grammer, says, "Writing a sitcom's not hard. You just have a married couple, a bar in Boston or a psychiatrist on the radio." This is a reference to both "Cheers" (1982) and "Frasier" (1993), both of which starred Grammer as Dr Frasier Crane.

Sherlock: The Empty Hearse (2014)
(TV Episode)
Writer Mark Gatiss has compared Mycroft and Sherlock to Frasier and Miles: "Sherlock and Mycroft are like Niles and Frasier Crane - they have very ordinary parents. And Sherlock is more likely to be a product of a lovely family than a broken family."
